Jurassic Knot Therapy Sand

Therapists that move their sand trays often will love Jurassic Knot Sand because it is a lightweight alternative to sand. Made from USA-grown corncobs, it weighs only 1/3 of the weight of sand which means it's a snap to carry to home visits or location-to-location!

It has a rough texture, bigger grain size than sand, and pleasing all-natural golden grain color. While dry use is recommended, we know water doesn't affect it. Please note: Knot sand is sold by volume not weight; this means the 8 lb size of Knot Sand = the volume of 25 lbs of sand and the 16 lb size = the volume of 50 lbs of sand.

Shipping is only $8 on any sized box of Jurassic Sands!

If the color isn't your key selection feature we suggest considering our other sands that have proved exceptionally popular with therapists. They are in order of popularity: Original Jurassic with its beautiful orangy-red color and silky clean texture, Mojave Beige if you are seeking a natural looking earthy neutral colored sand or either of our Sparkly White StarDust sands which have perfect texture and cleanliness.

FYI, just a quick note on our other sands so you have the complete picture of how they fit into your practice. Our RiverBed sand has slightly larger grains and therefore brushes off hands the easiest. Real QuickSand is just that and clinically relates to clients who metaphorically feel like they are sinking or stuck in quicksand. Purple Pink Garnet has no clinical connection that I am aware of but it has a powerfully attractive color and gemstone quality.

Now for the fundamentals you need to know. All of our therapy sands come in the following sizes: quart and half-gallon bags for those that want the sensory, grounding aspect of sand and want to fill a small bowl or tray. (We also sell just a cup of our gemstone sands Sparkly White StarDust and Purple Pink Garnet).

Next up in size is our 25 and 50 pound boxes. Remember, regulation-sized sand trays need 50 pounds to fill them to the mid-point while the 25 pound box is ideal if you are using an alternative container like a Rubbermaid tote or just topping off what you've lost over the years.

As far as shipping cost, everyone knows sand is heavy and heavy normally means it's expensive to ship. In order to save you money, we subsidize the majority of the cost of shipping and only charge you a flat rate price of $8 per box !

We are thankful for the US Postal Service Priority Mail because they not only make shipping of sand affordable, they are fast like us. You can expect to receive your order within about 3 to 4 business days after pressing the 'buy' button on our website.

And finally, we believe in doing business the old-fashioned way. That means if you have a question, issue or problem, we have Robin on the phone so you can talk to a real live person. Let us know if we can help with your sand tray needs...

Best regards - Geologist Jerry aka The Jurassic Sandman

We first started selling Jurassic Knot Sand in 2008 when customers asked us to find a sand that was lightweight and had a coarser texture than our silky-soft desert sands. Teachers and play therapists wanted something for their sensory bins and sand trays that wasn’t as heavy as regular sand, and had a different sensory experience to stimulate the inquiry aspect of learning. Jurassic Knot Sand met both of those requests.

To put the weight of different materials in perspective, consider this: a bag containing volume equal to 50 lb. of Jurassic desert sands would only weigh 16 lb. if filled with Knot Sand. This is because Knot Sand is made from the inside core of USA-grown corn cobs which is much less dense than play sand. Geologist Jerry Bergosh never realized how much corn is grown in the US until he rode his bicycle across Iowa in the summer of 2015.

He had the opportunity to meet farmers who have had farms in their families for over a hundred years and discovered the cornfields in Iowa are immense in size. Riding his bike 60 to 80 miles a day, day after day for a week he passed little towns surrounded by cornfields in every direction. Iowa is the #1 corn growing state in the US with 2.5 billion bushels each year – that’s enough corn to fill the Empire State building over 100 times and would weigh over 125 billion pounds. That’s a lot of corn!

And to his amazement, the rows of corn were so perfectly straight, he could see daylight between 6 ft. high rows of corn for more than a mile, then the corn disappeared over a gently rolling hill! The farmers told him they had satellite systems (GPS) on their tractors which made the perfectly straight rows. In town where the tractors were sold, he also found out the tractors cost a quarter of a million dollars each and were equipped with air-conditioning, radio’s and other luxuries.
